“…Higher concentrations of pilocarpine can cause tachycardia, bronchospasm and sweating. [43][44][45] Acetylcholine (1% for intraocular irrigation) is occasionally used to prepare the eye for anterior segment surgery requiring rapid, complete miosis. Acetylcholine solution can theoretically cause resistance to non-depolarising muscle relaxants.…”

“…50 Although anticholinergics, given as antisialogogues, have little effect on IOP when given intramuscularly before the arrival at the operating theatre or intravenously at induction, atropine should not be used in the presence of narrow chamber angles. 45 Propofol administered during induction of anesthesia causes a significant decrease in blood pressure, which is especially important for the elderly. Ephedrine has both α and β adrenergic properties and is helpful in the treatment of hypotension, but is better to be avoided because of the possibility of AACG.…”

Elevated intraocular pressure (IOP) causes structural changes in the optic nerve head in glaucoma patients. IOP reduction is clearly the only available treatment that has been proved to decrease both the risk of disease onset and its progression. Glaucoma surgery is indicated when maximal tolerated medical or laser therapy has failed to lower IOP. Anesthesia techniques for glaucoma surgery include general, retrobulbar, peribulbar, sub-Tenon's, subconjunctival, and topical anesthesia. General anesthesia may be advantageous for glaucoma surgery by avoiding the risks of regional anesthesia besides the total immobility of the patient, possibility to control the intraocular pressure, and the facility to fixate the operated eye. Anesthesiologists should be aware of the systemic side-effects and drug interactions of topical or systemic glaucoma medications. In addition, the effects of the anesthetic manoeuvers and drugs on IOP must be taken into consideration.

SAQs for the Final FRCA is an invaluable guide to the Short Answer Question paper for the Final FRCA examination, providing 9 papers of 12 questions per paper. Each question is accompanied by a full model answer structured using a star system to indicate the essential, desirable and supplementary information. Most answers also carry references and additional notes giving insight into why a question was written or what the examiner was really after. A highly informative FAQ section gives advice on all aspects of exam preparation. The book is laid out to enable the candidate to practise sitting whole papers of 12 questions or to attempt individual questions. Written by a group of authors who have either just successfully taken the Final FRCA or are regularly involved with training anaesthetists via the Frenchay Final FRCA Crammer Course, SAQs for the Final FRCA is an invaluable tool for your exam preparation!
